MIGS - a simple graphics utility program

A computer simulation model is currently being developed to forecast the vertical and lateral movement of cyanobacteria in lakes and reservoirs. Cyanobacteria actively regulate their position vertically within a water column by changing their buoyancy state in response to changing photosynthetic rates. Additionally the cyanobacteria are liable to lateral movement due to wind-induced currents and turbulence in the surface layers. Both the buoyant velocity and the turbulent velocity depend upon the hydraulic characteristics of specific water bodies. Lake width determines the depth and velocity of turbulence and lake depth will affect light attenuation and consequently photosynthetic rates.
